Liquefied natural gas

(LNG) is natural gas transformed into a liquid phase at a temperature below critical. LNG is a cryogenic fluid produced from natural gas by refrigeration down to condensation temperature −161.5°С. Temperature of crystallization is minus 182.5°С, density – 0.42 kilograms per liter. It is produced, stored and transported by specialized cryogenic equipment. The main LNG advantage is that the volume of gas is reduced 600 times. Practically, it means that the same volume contains 3 times more LNG than compressed natural gas (CNG) at 20 MPa pressure. For example, a 50 liter automobile gas cylinder in normal conditions and at 20 MPa pressure contains 10 to 12 cubic meters of natural gas in a gaseous phase, which is equal to 12 to 15 liters of gasoline. LNG is produced in liquefaction facilities by refrigeration and cryogenic cycles, including the use of energy from pressure difference at gas distribution stations (GDS) and at compressed natural gas (CNG) filling stations.
